Bioluminescence and Creatures of The Deep

Dive deep into the inky blackness of the Earth's oceans you may be lucky enough to encounter The Dana octopus squid. The odds of a sighting is increased due to it's increased due to it's luminous organs called Photophores.

These photophores are not exclusive to squids either. In the twilight zone of the ocean, where sunlight fades into blackness,  bioluminescence reigns supreme.



In the realm of fantasy, the use of bioluminescence can add a layer of intrigue to your narratives. Consider a glowing monster appendage flaring around in the melee and darkness, it's radiant form casting long, dancing shadows that confuse and obfuscate the shadows in the darkness.

It also stands to reason that in subterranean environments that persist for ages, filled with danger, the evolutionary pressures might inspire adaptations that shed a little light.

Terrifying creatures can also be dazzling and beautiful, to a distracting degree, so give me a Will save to figure out which shadow is a tentacle!

My Appendix LP Album Playlist

I started making an "Appendix LP" playlist after the supplement Iron Falcon 75 by Chris Gonnerman dropped at the end of December 2022. It's hard to describe this module without spoilers. Roughly I think an elevator pitch might be Stranger Things, but with adults in the 1970s. The content itself, unsurprisingly, takes place in 1975. Why 1975? Because that's when we have the thief from the Greyhawk OD&D supplement. I found it really inspiring, both the concept and the setups in the book and found myself wanting to be able to run a great campaign, and part of this was finding music to go along with it. Imagine a semi-finished basement in the Midwest. It is the end of summer 1975. The nicotine stained wood paneling, like the shag carpet underfoot, is a medley of earthy oranges and browns, each thread bears witness to countless family gatherings, holding tight the remnants of RC Cola "pop" stains and the occasional cigarette burn. If there was a TV it probabl

Radioactive Diamond Batteries

I've recently been reading about Radioactive Diamond Batteries , and of course my first thought is always straight to Gamma World and Sci-Fi TTRPGs.  This tech is a gammavoltaic, powered by the radioactive decay of the nuclear waste housed within. Why diamonds? Diamonds are excellent semiconductors, and they also do a good job of containing the radioactive material so it doesn't leak out. Think of the diamond as both the conductor and the protective shell of the battery. The games that pop in my head every time I run across an article about these cells are Gamma World, Mutant Crawl Classics, and even Mothership. Nuclear waste leans hard into the irradiated science fantasy settings, and the long life is well suited for a functioning technological artifact. And frankly, it's got GAMMA in the name! There are limitations to this tech that keeps it from being "game breaking", and that is while the batteries last a very, very long time (up to 28,000 years!). They are ex
